Class not found while using rmic.exe
This is my first RMI program, so bear with me.
After compiling both my object interface class file and my object implementation file (both with no errors), i move on to create the stubs/skeletons (or whatever they are called). After executing rmic MyObjImplementation, i get an error saying the following - "error: Class InputDeviceImpl.class not found."
I dont understand this, the .class file is indeed in the directory, and i know the rmic.exe sees it because i have tried to type "rmic *.class" and it gives the same error for every .class file in the directory.
whats going on?
-joey
well i figured out to compile the program, but i still dont understand what happened. I read the tutorial on this website, and it told me to start the rmi registry first. So does this mean that i have to do this each and everytime?

DataSetData class not found while Using Streamable Data Set
Hi
I am trying to populate a gridcontrol with the help of a DB
servlet.The servlet has a querydataset on the server side.
According to the online document i.e using " Streamable
DataSets" I am trying to use the class DataSetData and the
method DataSetData.extractDataSet.
The document says:
"The server may use JDeveloper QueryDataSets to provide the data
to the server machine. The data can be extracted using
DataSetData.extractDataSet and sent over a
wire to the client.The DataSetData object implements the
java.io.Serializable interface and may subsequently be
serialized using writeObject in java.io.ObjectOutputStream and
read using readObject in java.io.ObjectInputStream. This method
turns the data into a byte array and passes it through sockets
or some other transport medium. Alternatively, the object
can be passed via Java RMI, which will do the serialization
directly."
I searched for this class the entire JBCL package and also other
packages.I could not locate the class and the constructors and
methods that I can use.The explanation in the online document
about this is also trivial.I have no idea on how do I use this.
I need some information on how to use this class.
I also need some info on the data access and exchange between
JBCL controls on the applet and servlet like how do I stream a
querydataset such that I can populate my grid control.
Thanks

Class not found only using browser.
I can not run any of my java programs in my browsers. They work fine using the "java" command in a dos window or using the "appletviewer" command. But when I try to view them in a browser, the page appears to load fine but I get no program and the status window of the browser displays a class not found msg.
I've checked spelling, location, capitalization. Everything works fine outside the browsers but will not view in a browser. We had the same problem in school and the instructor just said to stick with the appletviewer for class.
I am running JDK1.2. Any suggestions?
JohnMaybe you should try a newer JAVA version.
I had a similar problem, but with a (too) newer JAVA version.
Problem:
You're compiling your applets with a quiet modern compiler (i.e. Netbeans Version 3.5.1)
You are able to compile your applets without any problems but if you try your applets in "real life", the browsers can't interpret your applets [class not found]. (I tested Internet Explorer 6.0 and Netscape Navigator 4.7)
So you need a plugin for the new JAVA environment because the JAVA environment of the browser is older than that which the applet needs.
Well, you have the choice to demand to every user of your applet to download the new Java Runtime Environment, but then don't wonder why nobody visits your site!
But, don't worry: I figuered out another solution, that Netbeans (www.netbeans.org) allows to compile in different JAVA versions.
Solution:
What you have to do is:
- Install a previous version of JDK (i.e. JDK 1.3 - I would suggest, lower versions don't work with Netbeans 3.5.1 and JDK 1.3 is enough for IE 6.0 and NN 4.7, which I tested)
- Go into the "bin"-directory of Netbeans (i.e. c:/netbeans3.5.1/bin)
- Open the file "ide.cfg" (with notepad or any other texteditor)
- You see a line like: jdkhome "C:\java\j2sdk1.4.2" -J-Xmx96m -J-Xss1024k -J-Xms24m -J-Xverify:none
- Change the path to your other JDK you wish, like: jdkhome "C:\java\jdk1.3" -J-Xmx96m -J-Xss1024k -J-Xms24m -J-Xverify:none
- That's it, you can compile your applets in a previous version of JAVA so that "older" browser user don't have to install a plugin for the new JAVA environment.
Have fun!
If you have any questions I would be pleased to help you.
If this tip helped you already I would be pleased if you would send me a quick email with your experience.

IOException File not found - While using Runtime.exec
Hey All,
I have written a Java application which needs to start up another external application. I have executables for that external application for different platforms (Win32, PPC and Linux). When the Java application is started it detects the OS and starts up the right executable according to the OS. The executable loads up fine on Windows without any problems. But in both Linux and Max OS X I get this exception:
java.io.IOException: java.io.IOException: "/home/vilas/Documents/Project/build/CLISP/linux/lisp.run": not found
at java.lang.UNIXProcess.<init>(UNIXProcess.java:143)

If I copy the string (/home/vilas/Documents/Project/build/CLISP/linux/lisp.run) and paste it in a terminal and press enter, the application starts up fine without any problems!! Can you please tell me what could be going wrong?
The following extra information maybe helpfull:
1) I use the exec(String command, String[] envp, File dir) version of exec.
2) The complete format of the command is as follows (one long string):
"/home/vilas/Documents/Project/build/CLISP/linux/lisp.run" -B "/home/vilas/Documents/Project/build/CLISP/linux" -M "/home/vilas/Documents/Project/build/CLISP/linux/lispinit.mem" -i loader.lisp
Thanks in advance for your time and efforts.I found the problem after extensively searing the forums (looking upto page 4 !! of the results). The problem was that I was using quotes to surround the paths in the command. If you copy and paste it in a terminal it will work fine but it does not work with runtime.exec. I am not sure, but I think the reason is that when a terminal is used, some pre-processing of the commands take place before they are passed onto the OS(shell). But while using runtime.exec, that pre-processing is not peformed and therefore some things will not work.
In order to fix the problem, I use quotes only when the OS is windows. In other cases(OS X, Linux) I escape the spaces i.e. replace " " with "\ ".
PS: The executable is a binary compiled from C code. -
Class not found when using JvmModelInferrer
I am trying to transform one of my language elements to a class using the ModelInferrer approach. This generated class should extend a class (AbstractMatcher) from an external project. The external project is added to the build path of the Xtext model project as an external class folder and to the run-time project in the same way. It should be noted that the external project is a plug-in built in Helios SR1. I am able to reference the AbstractMatcher class from the xtend source code (it is available for auto complete and imported correctly), but when I start runtime eclipse, I get a java.lang.NoClassDefFoundError when trying to add a superType to the generated class. If I substitute the AbstractMatcher with a dummy like java.util.ArrayList everything works fine. I have tried to make a simple Java class inside the runtime Java project and reference the AbstractMatcher from it and this also works fine. Everything seems to be able to find the offending class except the ModelInferrer.
import external.package.AbstractMatcher
def dispatch void infer(Matcher matcher, IJvmDeclaredTypeAcceptor acceptor, boolean isPreIndexingPhase) {
acceptor.accept(matcher.toClass("matchers." + matcher.name.toFirstUpper + "Matcher")) [
superTypes += typeRef(AbstractMatcher) // <---exception here

I sense that this is actually an OSGi problem, since I see this is how typeRef tries to find the reference, but I don't know how to get around it. I am not able to add the external plugin containing the AbstractMatcher class as a dependency and I'm not sure if it would be possible due to different Eclipse versions (Helios vs Luna).On 13.07.15 12:39, Zeljko Vukovic wrote:

Does it work for you if you refer to the AbstractMatcher from Java-code
that is in a project in the runtime instance?

Class not found in applet using 2 jar files
I have an applet which has been working for years as a stand alone or connecting directly to a derby database on my home server. I have just changed it to connect to MySQL on my ISP server via AJAX and PHP.
I am now getting a class not found error in my browser, probably because I'm stuffing up the class path.
The HTML I am using to call the applet is:
<applet code="AMJApp.class"
codebase="http://www.interactived.com/JMTalpha"
archive="AMJ014.jar,plugin.jar"
width="500"height="500"
MAYSCRIPT style="border-width:0;"
name="jsap" id="jsap"></applet>The AMJ014.jar contains the applet and supporting class files.
The error message is strange to me because it refers to a class I noticed on another web page but which has nothing to do with my applet. Anyway, the message in full is:

Make sure it's added to the build path and if necessary exported all the way to your JUnit project. -
Main-class not found error while clicking on the jar

Clicking on this jar, it is giving the problem main-class not found.
It contains the MANIFEST.MF file, with entry Main-Class: FinAlignTest for the main class.
FinAlignTest is my main class.
I have a similar jar created with a small swing application (Single file) clicking on it can open the swing application.
It is also attached above.Hi ,
My Apllication runs with out any warnings or errors. But when i create a jar file using eclipse it is giving this problem.
When i double click on the jar file i am getting this problem. MANIFEST.MF entry contains the main method entry.
I have created another jar (Which contains a simple java file, swing application) from eclipse export option.
It works fine on click.
But jar FinARM.jar contains 5 files (Swing app), which even fetch some data from the database.
My jar is placein the same machine where it can fetch data from DB
Can u plese tell me whats the problem.

nullI have created and published a EJB in Oracle 8i (in a particular
schema) by running the deployejb tool supplied. The ejb was
published successfully. On running the client program I get an
error saying that the mybeans's HomeHelper class cannot be
found. This error occurs when there is a lookup to the home
interface of the bean. The exception thrown says Reasons are
unknown. On checking the objects of type 'JAVA CLASS' I found
that the homeHelper class object had been created automatically
be the deploy process. What is the reason for the class not
found exception and what can I do to correct it. ?
